How Do I Plant Mushrooms Inside The Logs?

The simplest way to plant mushrooms, especially for a beginner, is to buy plug spawn. They are inexpensive, and are already inoculated with the mushroom. You simply have to drill holes into the mushroom log and hammer the plug spawn in. 

Drill holes about 6 inches apart from each other at about 1 inch deep. Depending on your log size, you should be able to plant anywhere from 30-50 plugs. Be sure to work in rows, staggering your holes after the first row. Place your next row of holes at least 2-3 inches below the first row, and continue this way. 

After your plugs are in, you’ll want to seal them with melted wax, such as cheese wax or beeswax.
